Abstract
A particulate filter (16) is provided within an inlet channel (22) of an ink jet (14). The filter is oriented generally in the direction of ink flow to provide a greater filter surface area. Positioning the filter within the inlet channel results in reduced acoustic crosstalk, more effective filtering, and more efficient purging of the filter itself because of the relatively high ink pressure drop across the filter in the channel. Positioning the channel vertically assists the buoyancy of the bubble movement during operation and purging.
